Square Inc (NYSE: SQ) is up another 5.5 percent since reporting a second-quarter earnings beat last week, and it now up an incredible 103.9 percent year-to-date.

Berkshire Hathaway Inc. (NYSE: BRK.A, BRK.B) stock gained 2 percent on Monday morning after the company reported yet another solid quarter of growth on Saturday.
